Abstract
Abstract A mosaic of semiconductor elements on an insulating base plate including interconnections made by two groups of parallel and alternating conductive strips and a plurality of conductors orthogonal to the conductive strips. Each of the conductive strips in one group is connected to selected semiconductor elements for excitation and each of the orthogonally disposed conductors is connected to a selected conductive strip in the second group and selected semiconductor elements for excitation. The device can be made compact and compatible for use in alphanumeric displays.
